A luggage wagon is being pulled with vector force v​, which has a magnitude of 700 pounds at an angle of elevation of 65 degrees
kipiarov [429]
The vector written in its components, by definition, is given by:
 v = lvl (cos ( \alpha ) i + sin ( \alpha ) j)

 Where,
 lvl: is the magnitude of the vector
 \alpha: is the elevation angle
 Substituting values we have:
 v = 700 (cos (65) i + sine (65) j)

 Rewriting we have:
 v = 700cos (65) i + 700sine(65) j

v = 295.8i + 634.4j
 Answer:
 
the vector v into components is:
 
v = 295.8i + 634.4j

Question 10 Please Help
svet-max [94.6K]

Answer:

1)· 5x + 2y = 9. First we solve for y. 2y= 9 -5x. y=(9-5x)/2. Now that we have the value of y. We substitute on the original equation and resolve. 5x + 2y = 95x + 2y = 9  5x + 2(9-5x)/2 = 9  5x + 9 - 5x = 9  9 = 9

That would be x = 1  

Now substitute and resolve to find y.  

5(1) + 2y = 9

5 + 2y = 9

2y = 4

y = 2

So our answer x=1 and y = 2. (1,2)

Proof :  

5(1) + 2(2) = 9

5+ 4 = 9

9 = 9

Step-by-step explanation:
